What is Fulcrum?

Fulcrum is betting its whole map stack on Esri, with a hard Google Maps cutoff on September 1.

Fulcrum is a field data collection platform, and nearly every entry in the last month touches mapping. The web app ships weekly fix batches for layer rendering (KML/KMZ, MBTiles, ArcGIS Feature Services), while iOS and Android push near-weekly builds against the ArcGIS SDK. The newest iOS build turns to app-level responsiveness - database queries moved off the main path and the record editor kept interactive while Photo FastFill works in the background.

What is ss3diags?

A fisheries diagnostics package that lives and dies by one upstream dependency.

ss3diags provides residual, retrospective and hindcast cross-validation diagnostics for Stock Synthesis models, sitting directly on top of r4ss. Its recent history is dominated by that dependency: when r4ss 1.50.0 renamed columns across its read and write functions, ss3diags pinned itself to 1.49.3 only, then spent the following release adapting. It now requires r4ss 1.50.0 and above and has moved to native R pipes.

Fulcrum is betting its whole map stack on Esri, with a hard Google Maps cutoff on September 1.

◆ Current state

Fulcrum is a field data collection platform, and nearly every entry in the last month touches mapping. The web app ships weekly fix batches for layer rendering (KML/KMZ, MBTiles, ArcGIS Feature Services), while iOS and Android push near-weekly builds against the ArcGIS SDK. The newest iOS build turns to app-level responsiveness - database queries moved off the main path and the record editor kept interactive while Photo FastFill works in the background.

◆ Where it's heading

The direction is a full consolidation onto Esri. The legacy Google Maps engine retires on September 1 with automatic migration for anyone who has not switched, and Esri now carries Google's satellite and street basemaps so the imagery argument is neutralized. Underneath, the mobile SDK moved to ArcGIS 300.0.0 and ONNX on-device inference gave way to a new INFERENCE format. Two capabilities are visibly staged behind early access rather than shipped: Photo FastFill, and a GPS integration still described as Alpha.

◆ Prediction

Expect the weeks before September 1 to stay dominated by migration-shaped fixes and Esri parity work, with Photo FastFill the nearer of the two early-access programs to general availability given it is already running in shipped builds.

0.0

A fisheries diagnostics package that lives and dies by one upstream dependency.

◆ Current state

ss3diags provides residual, retrospective and hindcast cross-validation diagnostics for Stock Synthesis models, sitting directly on top of r4ss. Its recent history is dominated by that dependency: when r4ss 1.50.0 renamed columns across its read and write functions, ss3diags pinned itself to 1.49.3 only, then spent the following release adapting. It now requires r4ss 1.50.0 and above and has moved to native R pipes.

◆ Where it's heading

The package is a downstream consumer whose release schedule is largely dictated by NOAA's r4ss. Between compatibility passes it has been shifting documentation from loose cookbook scripts into proper vignettes and shedding bundled Rdata in favour of objects generated at build time. Note that 2.0.3 and 2.1.0 were published the same day, so version order in this feed does not track chronology.

◆ Prediction

The next release most likely follows the next breaking r4ss change; between those, expect continued vignette and parameter-validation work.
